That makes sense. It's not empty talk that "seeing seedlings from childhood, knowing old age at three years old", because the six key growth periods of life all occur at three years old. Grasping the critical period of growth and educating children at the best time can make children grow up healthily and happily, stimulate their full potential and make them the best talents. From babbling to speaking, from toddler to running freely, children's body and mind develop rapidly in three years, and 3 years old is a milestone. Education experts point out that the age of 3 determines a child's life, and it is too late to start children's education from the age of 4 to 5. If you don't strengthen education before the age of 3, you can't guarantee your child's healthy growth in the future.
